Coms Support

Get Started with Coms

There are just a few things you need to do to start using Coms effectively - let's go through them one by one ...
Coms requires the latest Google Chrome, Firefox, Edge, Opera or Safari - there is no guarantee that it will function properly in any other browser. Best results are in Google Chrome for Windows or Android.


Access your Coms settings via the Settings button on the home page after logging in.
Settings contains:
  • Password
    Change your password here any time you want to.
  • Notifications
    We recommend that you select to Enable Offline Notifications. You will receive these notifications on your device when you are not logged in and when you are logged in but the Coms window is not onscreen.
    Notifications alert you to incoming calls, incoming messages and incoming contact requests.
    Web-push notifications are supported by all desktop and mobile browsers except Apple Safari.
  • Privacy
    Chatter Posts:
    Choose to make new Chatter posts public (visible to everyone), or private (visible only to Contacts). (Each post has a Privacy switch too).
    Avatar and Profile Statement:
    These are visible to anyone who visits your Chatter page, and you can choose to list your profile on the People page to be available for contact from anyone, or allow only your Contacts to see it.


You need to add your friends, family and work colleagues to your Contacts List before you can send messages or make calls. You can invite them by SMS (Google Chrome for Android) or request contact directly using their Coms usernames. Go to How to make a Contact Request and follow the instructions there.
For reasons of privacy and security you cannot import Contacts / Friends from other social media platforms - you should contact your friends there separately and tell them to sign up at, go to the Contacts page, and send a contact request to you.

Webcam and Microphone

To set up your webcam and microphone, go to How to make a Video Call and follow the instructions there.

Install the PWA (Add to Home)

Installing Coms PWA (also called "Add to Home") is *highly recommended because it enables Coms to run in a stand-alone window and behave like an app rather than the browser it's running in. Using push notifications it can alert you to new messages and calls when you are not onsite, it starts lightening-fast and it can operate partially without an internet connection too.
* not on Apple Safari:
Coms runs fine in Safari, but do not add-to-home on Apple devices because Safari's sub-standard PWA support can cause failures if the PWA is installed. On Apples, just launch Coms in Safari from your "frequently visited" collection.
Chrome for Android: Best In Class
In performance-tests of all functionality, Coms consistently performed best running in Google Chrome for Android or Chrome for Windows 10, in both cases running in PWA mode.
